This is what the ruling says:
"Many of concerns that the Claimant has, such as ensuring protection of vulnerable women, do not, in fact, rest on holding a belief that biological sex is immutable. It is quite possible to accept that transwomen are women but still argue that there are certain circumstances in which it would be justified to exclude certain trans women from spaces that are generally only open to women assigned female at birth because of trauma suffered by users of the
space who have been subject to sexual assault. This may be lawful under EqA where it is a proportionate means of achieving a legitimate aim.
"There might be circumstances in which a trans woman is recognised as an [sic] woman, but is not permitted to compete in sport on an entirely equal basis with women assigned female at birth, if that would create an unfair advantage.
"Many of the illustrations the Claimant relies on do not, in fact, rely on the belief that men can never become women; but on the analysis that there may be limited circumstances in which it is relevant that a person is a trans woman or trans man, such as when ensuring appropriate medical care is provided, which takes proper account of trans status.
"I accept that the Claimant genuinely holds the view that sex is biological and immutable. For her it is more that an opinion or viewpoint based on the present state of information available. Even though she has come to this belief recently she is fixed in it, and appears to be becoming more so. She is not prepared to
consider the possibility that her belief may not be correct."
This is a fundamentally idiotic position. If trans women really are women, why would it be acceptable to exclude them in certain circumstances? The only reason for excluding them is because of the belief that trans women are really male.
After her discussion of the legal elements of the case, Gaby goes on to say: "The central idea is that being a woman, trans or not, isn’t a licence to ride roughshod over the needs of others; that it comes with rights, but not infinite ones."
But of course there is no evidence at all that Maya rode "roughshod" over the rights of others. All she did was write some tweets stating that it isn't possible to change sex. Once again Gaby has either fundamentally misunderstood, or has understood but is misrepresenting, what the case is really about.
